Abstract

A medical or surgical instrument (30), such as a catheter, micro-catheter, guide-wire, cannula, blade, and forceps, comprising one or more sensors (82) to allow measurement of parameters around or within the instrument, and methods for making and using the same, are disclosed. Also disclosed are methods and apparatuses for measuring fluid characteristics, such as blood characteristics, including, for example, velocity, flow direction, and pressure in a vascular system.
